ABSTRACT:
A carpet cleaner with a base, a handle, and a plurality of wheels includes a suction opening, a fulcrum, a lever, and a cable line. The suction opening is provided at a front portion of the base of the carpet cleaner. The fulcrum is provided at a rear portion of the base of the carpet cleaner. The lever with an active end and a passive end is for levering the suction opening against the fulcrum. The cable line is extended from the active end of the lever toward the handle. The suction opening is pressed down to the carpet floor by the lever actuated by pulling up the cable line, and the suction opening makes tight contact with the carpet floor for facilitating suction of the carpet cleaner. The suction opening can be pressed down by a pressing bar attached to the base.
